Why you should care
Adding comments to the HTML code generally provides assistance to the developer but provides little practical use to the client as it does not increase user-friendliness since having commentaries on the source page could be a bit unnecessary.
It is recommended to avoid Incorporating HTML comments as it wastes time and resources which makes it hard to justify having them for the client as they would not understand the comments.
How we detect
This code insight shows that HTML comments will be visible for clients since clients generally don’t have a good understanding of the page’s source code. Since useful information for the client should be displayed in the page with the browser, it is unnecessary to place them as commentaries in the source page.
